DICOM CT Scans of Water-Injected Phantoms for RECIST and Volumetric Analysis

11 CT scans from a National Institute of Standards and Technology research article contain approximately 1250 slices per scan, each as a 512x512 grayscale DICOM image. The dataset includes DICOM files organized by phantom type and a mass.txt file listing injected water masses. It was last updated in July 2022.

Use Cases

• Develop algorithms for automated RECIST or volumetric measurement using the 512x512 DICOM slice sequences.
• Validate CT image segmentation models on the structured phantom objects, such as diapers (D1-D5) and vials (V2-V11).
• Correlate image intensity or texture features from the DICOM files with the injected water masses documented in mass.txt.
• Benchmark 3D reconstruction and visualization pipelines using the approximately 1250 slices per scan volume.

Strengths

• Contains 11 complete CT scan volumes, each with approximately 1250 high-resolution 512x512 DICOM slices.
• Includes a documented mass.txt file providing ground truth injected water masses for quantitative analysis.
• Data originates from the National Institute of Standards and Technology, supporting research reproducibility.

Limitations

• Small sample size of only 11 scans, limiting statistical power for training data-hungry machine learning models.
• No explicit columnar or tabular data is provided; analysis requires specialized DICOM processing tools.
• The dataset is static, representing a single experiment from a specific research article with no ongoing updates.
